This ReadyLIFT Block Kit is designed for 1999 - 2010 Ford F - Series trucks with Powerstroke engines. It safely lifts the rear of your 2WD/4WD Superduty. The OEM designs, made of high - quality materials instead of lightweight extrusions, give your truck a slight rake ideal for towing and hauling. It's a great option for stock, lifted, or leveled trucks. Part Number: 66 - 2294. Features include a slight rake for better towing and hauling, and it's a solid package for various truck setups. The kit includes OEM Style Cast Iron Construction Lift Blocks, four E - Coated Longer U - Bolts & Hardware, two 4' Rear Blocks, eight nuts & washers, integrated OEM Style Bump Stops, and a Carrier Bearing Spacer. Estimated installation time is 1.8 hours +/- 0.5 hours (excluding alignment and wheel & tire assembly). It's not for use with aftermarket or factory add - on air spring/load leveling kits attached to the bump stop tangs, and is for trucks with a Two - Piece driveshaft. ReadyLIFT offers a warranty, but note that off - road abuse voids it, and it doesn't apply to discontinued, clearance, or outlet products. Wearable components have a 1 - year coverage, and there's a free 5 Year/60,000 Mile Powertrain warranty.

Using this ReadyLIFT rear block kit is a great way to enhance your truck's performance for towing and hauling. First, make sure your truck is from 1999 - 2010 Ford F - Series with a Powerstroke engine. Before installation, check that you don't have an aftermarket or factory add - on air spring/load leveling kit attached to the bump stop tangs as this kit won't work with them. Installation takes about 1.8 hours, give or take 0.5 hours, but don't forget this doesn't include alignment and wheel & tire assembly. Just follow the included instructions to install the OEM Style Cast Iron Construction Lift Blocks, U - Bolts, Rear Blocks, nuts, washers, bump stops, and carrier bearing spacer. After installation, your truck will have a slight rake which is perfect for towing and hauling. For maintenance, regularly check the U - Bolts and hardware for tightness. Keep an eye on the wearable components like shocks, ball joints, etc. They're covered by a 1 - year warranty, so if you notice any issues within that time, contact ReadyLIFT. Remember, off - road abuse can void the warranty, so use your truck carefully. And if you have any questions, you can always refer to the ReadyLIFT website for more information.
